Healthcare provider-related perceptions toward deprescribing inappropriate medications among older adult outpatients.

To examine healthcare provider-related perceptions toward deprescribing inappropriate medications among older adults. A cross-sectional, correlational study used a convenience sample of outpatient older adults to measure their perception toward deprescribing using a Patient's Perceptions of Deprescribing (PPoD), which include 57 multiple-choice questions related to patients' sociodemographic data, health, medicines, healthcare providers, and experience of care provided by the clinic. Data were collected by a graduate nursing student from one pharmacy in a public hospital, five days per week, via in-person interviews. Data were analyzed for 200 participants. The level of patient collaboration with their primary care providers (PCPs) is linked to their trust in PCPs, beliefs about medication use, PCP knowledge, and medication concerns (p < .0001). Patient involvement in medication deprescribing decision-making is also associated with trust in PCPs and willingness to stop a medication (p < .0001). Additionally, trust in PCPs is related to patient involvement in decision-making, PCP knowledge, general health, collaboration with PCPs, and receiving conflicting information about a medicine (p = .010). Lastly, PCP medication knowledge is associated with trust in PCPs, views on the importance of medicines, medication concerns, seeking help with medicines, interactions with clinical pharmacists, and being advised by a clinical pharmacist to discontinue medication (p < .0001). The study found that older adults' trust in their PCP, collaboration with their PCP, involvement in the decision-making of deprescribing, and knowledge about medication are associated with clinical and medicine-related factors. Therefore, PCPs should discuss the benefits of deprescribing inappropriate medications to prevent long-term side effects. Future studies should focus on the effectiveness of evidence-based deprescribing protocols for older adults.

Transcriptomic evidence for atopic dermatitis as a systemic disease in NC/Nga mice

BackgroundIn the current study, we evaluated whether atopic dermatitis (AD) affects the entire body rather than being limited to skin barrier damage and inflammation. We hypothesized that medium-term exposure of distant organs to systemic inflammatory cytokines in sub-chronic inflammatory skin diseases has detrimental effects on distant tissues.ResultsOur findings demonstrated the dysregulation of genes and pathways associated with inflammation and the skin barrier, as well as genes and pathways involved in muscle development that respond to chemicals or stress in muscle tissues, all of which were reversed by hydrocortisone (Hc) administration. The expression of Ces1d showed significant differences during disease onset and after treatment in both skin and skeletal muscle, suggesting that Ces1d is likely responsible for the alleviation of subchronic AD.ConclusionsUsing NC/Nga mice with AD-like symptoms, we compared the transcriptomes of the skeletal muscle (a tissue that is relatively distant from the skin) with those of the skin (the lesion induction site) before and after disease induction, after which Hc was administered. Although further study is needed to better understand the effects of Ces1d on AD, skeletal muscle was associated with AD pathogenesis, and AD-like symptoms appeared to affect the body in a systemic manner. Given the importance of evidence-based medicine and the development of precision medicine, our findings provide insights into the mechanisms of AD onset and progression.

Capparis spinosa L. is a Mediterranean shrub and one of the most important species of the gender Capparis due to its ecological, medicinal and economic importance. This species has strong adaptation characteristics to regions with fluctuating climates. This work aims to evaluate the effect of the locality’s climate and plant’s parts on the content of polyphenols, flavonoids and antioxidant and antifungal activities of caper leaves and seeds. The present study was carried out in 7 localities in 2 Moroccan regions, Oriental and Fez-Meknes, where we collected leaves and seeds samples. Phenolic compounds were determined by the Folin Ciocalteu method, antioxidant activity was studied by DPPH and ABTS tests and an in vitro test of antifungal activity was achieved using Alternaria alternata. The analysis of variance showed no significant effect of locality, plant’s parts and their interaction on the phenolic compounds, antioxidant and antifungal activities of C. spinosa. Methanolic leaves extracts demonstrated the most favorable outcomes, yielding a maximum polyphenol content of 124.48 ± 0.05 mg EAG/g DW. Additionally, the maximum flavonoid content was recorded at 24.51 ± 0.01 mg EQ/g DW. The evaluation of the antioxidant activity showed that the minimum inhibitory concentration at 50 % (IC50) is 2.06 ± 0.05 mg/mL and 2.05 ± 0.02 mg/mL using DPPH and ABTS tests respectively. These extracts exhibited the highest % of inhibition, 30.59 % at 1000 ppm against A. alternata.

Ecotypic variation and environmental influence on saffron (Crocus sativus L.) vegetative growth: a multivariate performance analysis

Saffron (Crocus sativus L.) is a crop of significant medicinal and economic importance, exhibiting phenotypic plasticity that leads to variable vegetative growth. This three-year multifactorial study evaluated the vegetative potential of various saffron ecotypes under contrasting environments. The results revealed significant effects on shoot sprouting, leaf count, and overall growth, with the ´Tamlakoute´ ecotype (E2) performing best, particularly in the coastal field (CF2). The leaf count increased markedly from 24.9 ± 8.8 in the first year to 188.8 ± 43.9 by the third year, influenced by ecotypes and cultivation fields. In contrast, plant length variations revealed less dependence on ecotypes throughout the different growing seasons. Pearson's correlation analysis showed a weak relationship (r = 0.108, p < 0.004) between the number of shoots per original corm and per progeny corm. This implies a varied trade-off in resource allocation between vegetative growth and corm formation. The principal component analysis highlighted patterns of variations governed by environmental drivers, particularly favoring the E2 ecotype. Performance scoring and ranking, which assigned scores based on vegetative performance across all ecotypes by environment combinations, identified CF2E2 as the highest-ranking performer, followed by CF2E1 and CF2E4, with comprehensive scores of 2.4, 1.3, and 1.1, respectively. These findings highlight the potential of selecting superior ecotypes and coastal environments to promote sustainable saffron cultivation.

Association of adverse childhood experiences with adult-onset cardiometabolic conditions and prescription medicine use

Abstract Association of adverse childhood experiences with adult-onset cardiometabolic conditions and prescription medicine use Background and importance Adverse childhood experiences are potentially preventable and traumatic events that occur during childhood. Childhood exposure to trauma is highly prevalent and adults who had adverse childhood experiences are at increased risk of developing physical conditions. However, effect of adverse childhood experiences on health outcomes remains underrecognized. Aim Here, we aimed to measure the association of cumulative adverse childhood experience with adult physical condition and use of prescription medicines in general population. Methods We conducted a cross-sectional analysis using the population-based health study including 21083 participants at age 40 years or older. Self-reported adverse childhood experiences before age at 18 years, present or previous cardiometabolic conditions, and present or previous use of medications prescribed for cardiometabolic conditions were used in our analysis. Cox proportional hazards regression was used to estimate age, sex, smoking, education, and income-adjusted risk of cardiometabolic condition and prescription medicine use after adverse childhood experiences. Association of multimorbidity and using multiple prescription medicines with adverse childhood experience was analyzed using generalized linear model with ordinal classification. Results We found that having a history of adverse childhood experience was associated with increased risk of subsequent cardiometabolic conditions; hazard ratios ranged from 1.117 (95% CI, 1.054 – 1.185) to 1.341 (95% CI, 1.181 – 1.522). Furthermore, adverse childhood experience was associated with multimorbidity of cardiometabolic conditions (odds ratio [OR], 1.195; 95% CI, 1.117 – 1.279) and increased risk of using multiple prescription medicines (OR, 1.131; 95% CI, 1.057 – 1.210). Notably, we observed the dose – effect relationships of cumulative adverse childhood experience to the increased risk of 5 among 6 cardiometabolic conditions and to the increased risk of using 4 among 6 prescription medicines. Furthermore, cumulative adverse childhood experience had the dose – effect associations with multimorbidity of cardiometabolic conditions (ORs ranged from 1.120 [95% CI, 1.033 – 1.214] to 1.526 [95% CI, 1.276 – 1.825]) and using multiple prescription medicines (ORs are 1.393 [95% CI, 1.195 – 1.624] and 1.572 [95% CI 1.315 1.879]). Conclusions and relevance: Our findings implicate cumulative adverse childhood experience as a risk factor for later cardiometabolic conditions and use of medicines prescribed for cardiometabolic conditions. Our results are significant by suggesting inquiry into adverse childhood experience exposure during clinical consultations, services to alleviate the burden and increasing resilience in addition to strategies aimed at prevention of cardiometabolic conditions might improve health outcomes.

It identified precipitation in the wettest month, monthly mean of the diurnal temperature difference, and solar radiation intensity in April and July as the primary environmental factors affecting the suitability of E. sinica in the region. The areas of high, medium, and low suitability in the region cover 103,000 km2, 376,500 km2, and 486,800 km2. Under future scenarios, the suitability areas from 2021 to 2100 will decrease by 20%, with high suitability areas decreasing by 65% to 85% particularly. With comprehensive environmental variables, the suitability areas of E. sinica from 2021 to 2100 are projected, filling the gap in the projection of E. sinica suitability areas in the five northwestern provinces of China over long time period. The suitability areas show a significant decreasing trend. This research provides valuable insights into the suitability areas and crucial environmental factors, offering theoretical support for future protection and management efforts for E. sinica.

Polysaccharides and Peptides With Wound Healing Activity From Bacteria and Fungi.

Bacteria and fungi are natural sources of metabolites exhibiting diverse bioactive properties such as wound healing, antioxidative, antibacterial, antifungal, anti-inflammatory, antidiabetic, and anticancer activities. Two important groups of bacteria or fungi-derived metabolites with wound-healing potential are polysaccharides and peptides. In addition to bacteria-derived cellulose and hyaluronic acid and fungi-derived chitin and chitosan, these organisms also produce different polysaccharides (e.g., exopolysaccharides) with wound-healing potential. The most commonly used bacterial peptides in wound healing studies are bacteriocins and lipopeptides. Bacteria or fungi-derived polysaccharides and peptides exhibit both the in vitro and the in vivo wound healing potency. In the in vivo models, including animals and humans, these metabolites positively affect wound healing by inhibiting pathogens, exhibiting antioxidant activity, modulating inflammatory response, moisturizing the wound environment, promoting the proliferation and migration of fibroblasts and keratinocytes, increasing collagen synthesis, re-epithelialization, and angiogenesis. Therefore, peptides and polysaccharides derived from bacteria and fungi have medicinal importance. This study aims to overview current literature knowledge (especially within the past 5 years) on the in vitro and in vivo wound repair potentials of polysaccharides and peptides obtained from bacteria (Actinobacteria, Bacteroidetes, Cyanobacteria, Firmicutes, and Proteobacteria) and fungi (yeasts, filamentous microfungi, and mushrooms).
